Pollsters know about this, and the rule of thumb is that you can reliably ask people of what they currently do routinely, almost daily. E.g. if you ask them who they voted 10 years ago, they might remember it wrong. If you ask what they're gonna do, this is completely unreliable. In political polls, this is the only thing you can do. I guess, they have corrections for the real attendance of social/age strata. In deep interviews, the sociologists are more interested in how people explain their world picture and what they point at, and how react to questions, than to what they tell about themselves.
